Foldable Electric Bed Swivel Mount Design to Reduce Packing Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable electric beds have a bulky packing volume, leading to difficulties in transportation and storage due to their unsatisfactory thickness in the folded state.
Innovation Solution
A foldable electric bed design featuring a base mount, swivel mount, and actuator, where the swivel mount is pivotally connected to the base mount and can swivel between two positions, allowing the actuator to lift the elevational position of the second shaft, thereby reducing the overall thickness when folded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the electric bed is designed to be foldable to reduce packing volume, then transportation convenience is improved, but the thickness in folded state remains unsatisfactory
Solution Approach 1:
The patent applies dynamics by making the support frame pivotally connected to the base mount, enabling it to rotate between a support position and a folded position. This dynamic mechanism allows the bed to transition from a rigid bulky structure to a compact folded state, significantly reducing packing volume while maintaining structural integrity during transportation
Solution Approach 2:
The patent utilizes dimensionality change by repositioning the support frame from a vertical support configuration to a horizontal folded configuration against the base mount. This spatial transformation in another dimension reduces the thickness in folded state by utilizing the length and width dimensions of the base mount, achieving compact storage without compromising the support function when deployed
2Ease of operation
If the support frame is pivotally connected to reduce thickness, then storage convenience is improved, but structural stability may be compromised
Solution Approach 1:
The patent applies beforehand cushioning by providing a buffer spring that absorbs shock and maintains pre-compression on the support frame. This ensures that when the support frame is folded against the base mount, it remains firmly held in position without excessive movement or instability, while also protecting the pivotal connection from impact damage during storage and transportation
Solution Approach 2:
The patent utilizes parameter changes by employing a buffer spring that can be adjusted in terms of pre-compression force and stiffness. This allows optimization of the balance between holding the folded frame securely (improving storage convenience) and maintaining structural stability. The spring parameters can be tuned to provide sufficient holding force without causing excessive stress on the pivotal connection

Function Achieved in This Case
This design reduces the packing volume and enhances convenience in storage and transportation by minimizing the thickness of the foldable electric bed in its folded state.
Implementation Method 1
The swivel mount is pivotally connected with the pivot portion by a first shaft, such that the swivel mount is swivelable relative to the base mount
Implementation Method 2
The actuator has a first end pivotally connected with the swivel mount by a second shaft, and a second end pivotally connected with the first moveable frame, such that the moveable frame is drivenable by the actuator to swivel relative to the base mount

AI summary
A foldable electric bed includes a base mount having a pivot portion, and a swivel mount pivotally connected with the pivot portion by a first shaft, such that the swivel mount is swivelable relative to the base mount between first and second positions due to the limit of first and second contact portions of the base mount. An actuator has a first end pivotally connected with the swivel mount by a second shaft, and a second end pivotally connected with a moveable frame such that the moveable frame is drivenable by the actuator to swivel relative to the base mount. When the swivel mount is swiveled from the first position to the second position, a position of the second shaft is lifted.
